HENRY S. FIFIELD, OF NEW HAMPTON, NEW HAMPSHIRE.

IMPROVEMENT IN LAMPS FORCOOKING.

Specicatlion forming part of Letters Patent No. 204,144, dated May 28,1878; application filed 4May 18, 1877.

To all whom it may concern:

Be it known that I, HENRY S. FIFIELD, of New Hampton, in the county ofBelknap and State of New Hampshire, have invented a new and usefulImprovement in Lamps for Cooking, which improvement is fully set forthin the following specification, reference being had to the accompanyingdrawings, in which- Figure 1 is a perspective view of my lamp withoutthe cooking attachment, and Fig. 2a perspective view of the cookingattachment.

' In the drawings, A represents the oil-vessel, of any convenient form,a broad base being essential that it may stand securely.

B is a metallic base-plate, secured, by means of proper supports a', ashort distance above and to the top a of the oil-reservoir, and leavinga space, b, between the top of such oilreservoir and the bottom of thebase-plate, in which are conveniently placed the ratchets o, whichoperate the wicks. This base-plate B is provided with openings d, toadmit air through the space b for combustion, as will be presentlydescribed.

A supporting-plate, C, having perforations e, is secured above and tothe base-plate B by means of proper supports e'. This support--ing-plate C is made of thin sheet metal, is

somewhat smaller than the base-plate B, and has flan ges f bentoutwardly, and divided in numerous places, so as to present numerousspring portions g to-.rest against and hold more securely the cookingattachment, presently to be described.

The wick-tubes D pass through the plates B and C, and rise a littleabove the latter.

Upon the base-plate B the cooking attachment E is placed, resting uponsuch baseplate. This attachment is preferably made Vof suitable thinmetal, and has a base, h, an-

nular in form,`with vertical walls of such height that when theattachment is placed upon the lamp and resting upon the base-plate thespring-flanges g of the plate G will hold it steadily. This attachmenthas a body, t', preferably shaped like the body ofa globe orlamp-chimney, and upon that a flat top, j, With openings k, lfor the.escape ofthe products of combustion and the heated air. Within this topj is fitted a grating, l.

Near the bottom of the body i of the attachment is a mica window, m, toenable the condition of the light to be noticed.

'It will be observed, in the operation of my device, that the air forcombustion enters through the openings in the base-plate B, and passesthrough the perforations of the supporting -plate (l, where it isdelivered to the flame.

In the use of my apparatus, the wicks being lighted, and the attachmentbeing placed 'upon the lamp, the air in the interior of the attachmentbecomes speedily very hot, and the hot air and the products ofcombustion escape out of the top of the attachment. Now, any properdish'being placed upon the top j, water may be speedily and convenientlyboiled, or any cooking `may be' carried on.

The advantages of my construction for use in the sick-room, or in thesummer season when it is not desirable to use cooking-stoves, areapparent upon observation.

I am aware that lamps for cooking were.

well known before my invention hereinbefore described, and also lampswith separate and removable cooking attachments, and also cooking-lampswherein base and supporting plates were used 5 and I am not aware thatthere is novelty in any of the elements employed "by me; but I do notknow that the same elements as constructed by me have ever been used inthe same combination. Having thus -described my invention, what I claimas new therein, for which I desire Letters Patent, isg In lamps forcooking, the lamp A, provided with the plates B and C, and theattachment E, having a base, h, adapted to rest upon the plate B and beheld in position by the plate O, and having an enlarged body, i, and atop, j, adapted for a grating, the several parts constructed andarranged substantially as described and shown.
